  • Restores soil carbon
  • Conserves moisture
  • Saves fuel
  • Saves labor
  • Lowers machinery costs
  • Reduces erosion
  • Improved soil fertility
  • Controls weed
  • Planting on the best date
  • Improves wildlife habitat
  • Conservation practices to mitigate and adapt
  • NT wheat had 3.4 in. more water than CT wheat at planting.
  • 30% higher yield: 36 versus 28 buac-1
  • Enhanced soil organic matter content maximizes crop water use efficiency
  • Time of planting, seeding configuration and plant populations
  • Choice of crop species, depending on site-specific considerations
  • Vegetative barriers and terraces may enhance water storage, reduce evaporation, and minimize risks of wind erosion
  • Lal et a., 2012. Adapting agriculture to drought and extreme events. J. Soil Water Conserv. 67:162-166.Conservation practices to mitigate and adapt to drought and climate variability
  • Erosion prevention and protection from extreme weather events, which may be more damaging in the future.
  • Irrigation infrastructure to reduce water losses and increase irrigation efficiencies.
  • More diverse cropping systems to adapt to variable climates and new pest and disease pressures.
  • Develop crop varieties that are drought-tolerant and more resistant to heat stress, with higher N-use efficiencies.
  • 5. Improve the synchronization of planting and harvesting operations with shifts in the hydrologic cycle (rainy season). 6. Manage soil and crops to increase water-use efficiencies. 7. Value agricultural commodities for their water footprint or environmental traits. 8. Increase soil C sequestration to improve soil functions. 9. Increase N-use efficiencies for cropping systems. 10. Apply the concepts of precision/target conservation to increase conservation effectiveness across spatial and temporal variability. Chuck RicePhone: 785-532-7217Cell: 785-587-7215
